Kuqa Complex Surface Area Pseudo 3D Near-Surface Modeling and Static Correction Techniques

Abstract

Having been one of the key areas for hydrocarbon prospection of Tarim Oilfield Company, Kuqa Mountain in Tarim Basin has significant LVL survey, modeling difficulty and statics problems due to its diversified near-surface conditions. In this paper, the author makes an accurate analysis on the near-surface structure in the area using the uphole-constraint shallow-layer tomography LVL surface method, the pseudo 3D near-surface modeling and the comprehensive statics technology and therefore, the imaging of sections is improved, which provides a reference for the near-surface modeling and statics works in similar areas.
